6. Return to system view.
7. Enter Ethernet interface view.
8. Assign the Ethernet interface
to the specified aggregation
group.
Configuring BFD MAD
When you configure BFD MAD, follow these guidelines:
You cannot enable BFD MAD detection on VLAN-interface 1.
•
Do not use the BFD MAD VLAN for any other purpose. No Layer 2 or Layer 3 features, including
•
ARP and LACP, can work on the BFD MAD-enabled VLAN interface or any port in the VLAN. If you
configure any other feature on the VLAN, neither the configured feature nor the BFD MAD function
can work correctly.
The IRF fabrics in a network must use different BFD MAD VLANs.
•
• Do not enable the spanning tree function on any port in a BFD MAD VLAN. The MAD function is
mutually exclusive with the spanning tree function.
Do not bind a BFD MAD-enabled VLAN interface to any VPN. The MAD function is mutually
•
exclusive with VPN.
To avoid problems, do not use any other command than the mad ip address command to configure
•
IP addresses on the BFD MAD-enabled VLAN interface. For example, an IP address configured with
the ip address command or a VRRP virtual IP address can cause problems.
If an intermediate device is used, you must assign the ports of the BFD MAD links to the BFD MAD
•
VLAN on the device.
To configure BFD MAD:
Step
1. Enter system view.
2. Create
dedicated to BFD MAD
detection.
3. Return to system view.
4. Enter Ethernet interface view.
5. Assign the port to the BFD
MAD VLAN.
6. Return to system view.

Assign the port to the VLAN as a
trunk port:
port trunk permit vlan vlan-id
Assign the port to the VLAN as a
hybrid port:
port hybrid vlan vlan-id { tagged |

Choose one command
depending on the port type.
BFD MAD detection has no
requirement for the link type of
the detection port.
The default link type of a port is
access.
